JOHN D. HOOPER, OF NEW YORK, N. Y.

PAPER TRIIVHVHNG AND PASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 363,111, dated May 1'7, 188'].

Application filed September 9, 1886. Serial No. 213,117. (No model.)

To all whom it may concern- Be it known that I, JOHN D. HOOPER, of the city, county, and State of New York, have invented a new and Improved Paper Trimming and Pasting Machine, of which the following is a full, clear, and exact description.

This invention. relates to the construction of i a combined trimming and pasting machine that is more especially applicable for use in the cutting off of the surplus edge of wallpaper and in applying paste to the back of the paper prior to the application of the paper to the wall of the apartment or room which it is intended to cover.

My invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of my improved form oftrimming and pasting machine. Fig. 2 is a side view of the machine, and Fig. 3 is a cross sectional View taken on the line w an of Fig. 1.

In constructing such a machine as the one illustrated in the drawings above 'referrcd to, I provide two side plates or frames, 10, between which there is mounted a paste trough or tank 11. \Vithin the tank 11 there is mounted a paste-supply roller, 12, which is covered with any proper form of fibrous material, such as felt, and arranged so that its peripheral face will bear against theperipheral face of a distributing roller, 13, which is mounted in bearings formed in the said plates or frames 10, the shaft 141 of this roller being the main shaft of the machine and carrying a gear, 15, which meshes with a gear, 16, that is carried by the shaft of the roller 12, as clearly shown in Fig. 2.

At one side of the trough 11 there is a chamber, 17, within which there is fitted a casting, 18, said casting being formed with two slots or openings, 2 and ,3, and arranged with fixed bearings which support a roller, 19. Above the roller 19 there is mounted a second roller, 20, mounted in movable boxes or bearings which ride in inclined slots or openings, 4, as best shown in Fig. 3, the roller 20 being normally depressed by springs 21, so that it will bear against the surface of the roller 19, while the tension of the springs is governed and controlled by set-screws 22. It will be noticed that the casting 18 is formed with downwardlyextending wings 23 and 24, which fit within the chamber 17, the wing 23 hearing against the inner face of the rear wall of the chamber, while the wing 24 rests against a cross-bar or scraper, 25, the edge of which bears against the peripheral surface of the roller 13.

A shaft, 26, is mounted in bearings that are held to the side frames by tap-bolts 27, and this shaft 26 carries a circular double-faced knife or trimmer, 28, the said knife being adjustably mounted upon said shaft, to which it is held by a set-screw, 29. The shaft of the roller 20 carries a gear, 30, that is engaged by the gear 15 of the shaft 14, and the shaft 26 carries a gear, 31, which gear 31 is driven through the medium of an idler, 32, that is mounted as is best shown in Fig. 2. In advance of the roller 13 there is mounted a guiding-roller, 34, beneath which there is a guard or shield, 35, and in advance of the roller 31 there is a shaft, 36, which carries adjustablymounted guides 37. The shield 35 serves as a stripper, preventing the web from adhering to the roller 13, and causing it to pass directly to the roller 34.

The roll of paper to be operated upon is placed upon a rod or shaft, which is mounted in bearings 40, and from this rod the web of paper is led over a guide-roller, 4.1, beneath the circular cutter 28, Which acts in conjunction with a cutting-block, 412, that is adjust-- ably mounted upon. a rod, 44, said rod being arranged directly beneath the shaft 26. In addition to the block 42 the rod 44 carries a guiding-block, 45, said block being formed with an upwardlyextending flange, 16, which serves as a guide for that edge of the paper which is not to be trimmed. After passing the knife 28, the web is led between the rollers 19 and 20, which are the feeding-rollers of the machine, and from these rollers up and over the roller 13, and under the guiding-rollcr 34, the guidingfingers 37 being adjusted so as to properly guide the paper as it issues from the machine.

In order that the shaft of the roller 13 and the parts carried by the casting 18 may be held against displacement, I have provided clamping-arms 50, one of said arms being connected to each side plate or frame by a pivot bolt or pin, 51. These arms 50 are formed with notches 52, which fit over the shaft 14:, and with other notches, 53, within which the extending ends of the shaft of the roller 20 fit. The rearends of the arms 50 are formed with recessed ends or projections 54, the parts being arranged so that the shanks of set screws 55 will enter the recesses in the arms 54 when the parts are in the position shown in Fig. 2, so that by turning the set-screws home the arms 50 will be clamped to the side frames of the machine.

When it is desired to remove the roller 13 and the casting 18 for the purpose of cleaning the machine, the set-screws 55 are loosened and the arms 50 are thrown back, after which it will be seen that the roller'and the casting may be lifted out of place. In the movement described the shaft 14 is 20 turnedthrough the medium of a crank-arm, 56, which is secured to one end of the shaft. In order that all retrograde movement of the roller 13 may be prevented,which movement, it will be understood, will be apt to carry the web of paper downward through the trough or tank 11, I provide a gravity-pawl, 58, which is arranged to engage, with the teeth of the gear 15, this pawl being mounted upon the shank of one of the set-screws 55, or upon any other proper stud or pivot.

When the machine above described is operated in the manner hereinbefore set forth, the knife28 should be set so as to cut the surplus edge off from one side of the paper,

after which the paste will be applied through the medium of the roller 13, and the paper .passing forward beneath the roller 31 the end of the web may be fixed upon the wall and the paper applied thereto, being cut off to proper length after it is hung up on the wall.

Now, although I have described this machine in connection with the trimming and pasting of wall-paper, it will of course be an derstood that the machine may be used for many other purposes; and it will also be understood that, although the scraper 25 is a desirable feature, it is not essential to the operation of the machine, as the delivery of the Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the trough and pasting-roller, of a removable frame or castwalls for the'passage of the paper, and two feed-rollers between which the paper passes substantially as set forth.

2. The combination, with the paste'trough having a chamber, 17, in its rear end, and notches 52 in the upper edges of its opposite sides, and the roller having a shaft the ends of which rest in said notches and project beyond the trough, of a removable frame or casting having feedrollers journaled therein, the shaft of the upper roller projecting beyond the ends of the frame, and arms, each pivoted at one end to the frame, engaging the projecting ends of the said two shafts, and means for locking the free ends of the said arms, substantially as set forth.

3. In a paper pasting and trimming machine, the combination of the following elements: rollers 12 and 13, mounted within a trough, 11, rollers 19 and-20, mounted within the casting 18, a shaft, 26, carryinga knife, 28, a guiding-roller, 34, and a mechanism, substantially as described, whereby a rotary motion is imparted to the rollers and to the knife-carrying shaft.

4. In a paper trimming and pasting machine, the combination,with the paste tank or trough 11, of a roller, 12, mounted within the trough,a roller,13, mounted in bearings formed by the side frames of the machine, advancingrollers 19 and 20, a trimming-knife, 28, adjustably mounted upon its shaft, an adjust able block, 42, arranged in connection with the shaft, an adjustable guide, 45, formed with a flange, 46, a guiding-roller, 34, and guidingarms 37, substantially as described.

5. The combination, with the shaft 14 and the castinglS, of the clamping-arms50, formed with recesses 52 and 53, and a projection, 54, a set-screw, 55, being arranged to enter a slot formed in the projection 54, substantially as described.
